However, no synthetic nematicide is currently registered for ratoon sugarcanes under Japanese regulations. Furthermore, there is a potential risk that nematicide use could harm non-target free-living nematodes, which may contribute to soil health and fertility. To address these challenges, we investigated the nematicidal efficacy of the insecticide fipronil, which interferes with GABA receptors, against root-lesion nematodes, aiming to improve yield and quality in ratoon sugarcane. Simultaneously, we assessed its potential side-effects on the non-target free-living nematode community. We first determined an appropriate dose of fipronil to control root-lesion nematodes in ratoon canes in pot trials. We then conducted multi-year field experiments to assess a yield response to fipronil treatment and its side-effects on the soil nematode community using metabarcoding analysis with next-generation sequencing. Fipronil treatment significantly decreased root-lesion nematodes in ratoon cane roots (42–51 % to control) three months after application, resulting in significant increases in yield by 4–20 % and Brix value by 2–3 %. Impact of fipronil on the abundance of soil nematodes and their community structure was negligible, as revealed by metabarcoding analysis. Diversity indices, functional metrics, and maturity index showed no significant difference between treatments. Furthermore, principal component analysis and differential abundance testing (ANCOM-BC) showed no dominant and impacted nematode taxon due to fipronil treatment. Our findings suggest that fipronil (0.3 kg a.i./ha) is appropriate to control root-lesion nematodes in ratoon sugarcane, providing yield increase without evident side-effects on the overall non-target nematode community.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"199 ","pages":"Article 107403"},"PeriodicalIF":2.5,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify which grain characteristics impair <em>S. granarius</em> performance and to describe the biological cascade by which host traits affect the nutritional physiology and population growth of the pest. Ten barley cultivars differing in grain hardness, protein, starch, and moisture content were evaluated. Pest responses were assessed using life history traits, nutritional indices, and digestive enzyme activity. Marked differences in pest fitness were observed among cultivars. A trait–physiology–performance cascade was used to interpret resistance patterns. Strong negative correlations were found between grain hardness and protein content with fecundity (<em>r</em> = −0.821), intrinsic rate of increase (<em>r</em> = −0.789), and <em>ECI</em> (<em>r</em> = −0.738). Digestive enzyme activity did not correlate with pest success, indicating limited physiological plasticity. These results support a mechanistic model in which grain traits trigger a cascade of physiological impairments, ultimately limiting the fitness of the pest. Barley resistance to <em>S. granarius</em> emerges from sequential biological effects, beginning with grain traits and culminating in reduced population growth. Resistance in specific barley cultivars arises primarily from physical and nutritional characteristics, particularly hardness and protein content, rather than enzymatic interference. This cascade provides a practical and cost-effective approach for resistance screening and cultivar deployment in postharvest IPM systems.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"198 ","pages":"Article 107400"},"PeriodicalIF":2.5,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies were conducted at Muzaffarpur in Bihar state of India during during 2022–2024 to assess the effectiveness of ten fungicides, including azoxystrobin, trifloxystrobin, pyraclostrobin, difenoconazole, tebuconazole, thiophanate methyl, metiram, carbendazim, mancozeb, and copper oxychloride, and various combinations. Residue levels of selected fungicides were also analyzed for safety standards compliance. The fungicides were applied at recommended dosages ranging from 0.3 to 2.0 g or ml per litre of water on litchi trees thrice-first after panicle initiation, second immediately after fruit set, and third at colour-break stage. Fungicides residue assay was carried out in a ‘planned experiment,’ and also in some ‘random retail samples’ from Muzaffarpur and Patna districts of Bihar, India. The results showed that fungicide application significantly reduced the incidence and severity of panicle blight, fruit blights, and anthracnose, thereby protecting both panicles and developing fruits in litchi trees. Thiophanate methyl was found to be the most effective, with a minimum percent disease severity index of 5.93 in 2022 and 7.81 in 2023. Thiophanate methyl-treated trees recorded the lowest incidence of fruit blight and anthracnose (0.0–0.50 %) during both years, compared to significantly higher levels in control trees (5.50–8.50 % fruit blight and 5.83–6.37 % anthracnose).

Thiophanate methyl had the highest overall disease control and recorded the highest incremental cost benefit ratio (5.52–5.63) for the complete spray schedule targeting multiple diseases.

Integrated management strategy, combining cultural and chemical tactics, offers an alternative control measure with multiple advantages. Field experiments were conducted in 2020 and 2021 at Arba Minch (AM) and Mihirab Abaya (MA) in southern Ethiopia to evaluate the effectiveness of integrating cultural practices (earthing-up) with various ratios of different insecticide sprays in reducing leafminer damage, minimizing yield losses, and enhancing tomato agronomic performance. Twenty-two treatments were factorial arranged within a randomized complete block design with three replications. Results showed that three-time earthing-up combined with 50 % Spinosad and 100 % Nimbicidine significantly reduced larval populations (83.76 % and 86.99 %) and leaf-mining (75.84 % and 68.70 %) while lowering leaf damage (9.59 % and 10.07 %) and increasing marketable yield (46.96 and 48.52 t ha⁻¹) compared to untreated controls at AM and MA, respectively.
